In honor of the official naming of the scattered disk object formerly known as 2003UB313, I'm writing a short story called "The Fungi From Eris" (it's almost done, thanks).

Anyway, while trying to bring to my story the scrupulous concern for scientific accuracy that is the hallmark of the Lovecraftian style, I became curious about where Eris is, exactly. Fourmilab's Solar System Live orrery only shows the nine textbook planets, but you can show an additional object on the map by pasting in its orbital elements.

Orbital elements are sets of astronomical measurements that resemble the tables used to enforce copyright protection in old computer games. The orbital elements are published, Kilgore Trout-style, in dirty magazines such as the IAU's Minor Planet Electronic Circular. It is rawther difficult to use the IAU site to find the MPEC issue for a particular minor planet, but it's easy if you use a Google site: search. Eris's orbital elements were published in MPEC 2005-041, and they are as follows:
